i am using sHM since 2 years and after the 7th OF-Workshop I read the sHM-Tutorials of Eugenede Villiers after Bruno told in a thread this nice link.

In the presentation there is described the function of "featureAngle".
If you set it to 180 you are able to build layers on the corners. I tried this but there is no corner layer. I tried a few featureAngles like:

30
60
120
150
180

but every mesh looked the same?
Is that function just implemented in the extended sHM version?

just to give you an example:
I used a cube blockMesh background mesh. Then I put a cube inside this one with SHM and used a few layers.

Those layer-cells are colored green.

The 1st image is with "featureAngle 50" The 2nd is with "featureAngle 60". This can be a little confusing because the angle is not referring to the two neighboring surfaces the layercells rest on, but to the cells normal vectors of those two neighboring cells. And on a 90° corner that angle is not 90 degrees but less!

The last image attached shows how i think the featureAngle works.

Hi Jan,
thanks for your replay. Well your post sounds very good but I thought that you get better cells with the layer generation at the corners?
